AST preserved neuron survival and inhibited cell apoptosis in the spinal cord after SCII. a HE and TUNEL staining were performed in different groups. The number of neuron survival and the apoptotic index of anterior horn neurons are shown in b and c, respectively. Scale bar = 200 μm. Values are mean ± SD. ^*P < 0.05 versus sham group, ^#P < 0.05 versus SCII group, ^&P < 0.05 versus SCII+AST group
